Abstract
Example methods are provided a computer system to perform context-aware domain name system (DNS) query handling in a software-defined networking (SDN) environment. One example method may comprise detecting a DNS query to translate a domain name; identifying DNS record information that translates the domain name to a network address assigned to a virtualized computing instance; and identifying context information that is associated with the virtualized computing instance and mapped to the DNS record information. The method may also comprise: in response to detecting a potential security threat based on the context information, performing a remediation action to block access to the virtualized computing instance; but otherwise, generating and sending a DNS reply specifying the network address assigned to allow access to the virtualized computing instance.
